I also have the Lyman, but have no experience with any other.
There are many who have complained about them, and they do
have issues if one does not do maintenance on them, such as
periodically wiping them down with a used dryer sheet to rid
them of any static electricity. Using a cell phone while
operating them will drive the little 'puter chip in them
crazy, as will the old type of computer monitor. Following
a few simple rules, mine works flawlessly.
